Another case where output differs from ST_Intersection:

  Rectangle: 0,0 10,10
   Geometry: LINESTRING(10 0, 20 0)
   Expected: POINT(10, 0)
   Obtained: EMPTY

  +----------+
  |          |
  |          |
  |          |
  +----------O------------+

That is, the intersection of a rectangle and a linestring whose endpoint
is on one of its corners is expected to yeld the corner point.
